Thanks DanielRLee and Tek! (Tek: Yes; I definitely plan to adapt the tester to my final config.)
I agree that this is a useful tool. Though simple, it can quickly direct the trouble shooter in the right direction.
I'll share what I observed while testing a Leafbike 1500W stock kit with this tester.
Note1: When the system is connected as delivered all colors match the wheel runs forward.
Note2: Tek's great document explains some of the following observations. What I'm sharing here is 'what' you can expect when you slap this tester on a LeafBike system, out of the box (not 'why').
- Motor Phase Test:
Connected tester to motor phase wires; matched the colors. Turn wheel and all lights blink. Disconnect blue wire and light labeled 'blue' stops blinking (and so on). Good. Blinking too fast to discern order/direction. Maybe because this motor has 23 poles?
(Suggestion: A "tester-less" phase tester: Spin wheel with phase wires open; no cogging. Short any phase to any phase and spin wheel slowly; heavy cogging. So, if you have heavy cogging with the phase wires open, you probably have a phase short. If you short any two phases and don't get heavy cogging, you probably have an open in one or both of those phases. Opens can be isolated by playing with combo's.)
- Motor Hall Sensors:
Hall connectors and colors match out of box. Tester issues a 120 degree pattern (see tester instructions), but it's reversed.
- Throttle Test - Note that this feature is called "Steer" on my tester. Works just as advertised on this throttle.
- Controller Phase Test:
Hall connectors and colors match out of box.
The tester's "5 Volt" LED blinks (as stated in the instructions). (Looked like a problem to me...)
LED's light in adjacent pairs during test. It's possible that one LED across from the lit pair lights dimly, also.
Instructions say if two phase test LED's light at the same time, the controller is bad. Not the case!
Sequence is counter-clock- wise.
After twisting throttle, the LED sequence starts and makes about 1 rotation and then stops by itself (logical; probably the controller giving up; just sayin).
Sequence rate is fixed (about 2 Hz) but as throttle is twisted more, LED' pairs get brighter.
Q: Could adjacent pairs mean 120 degrees and opposing pairs mean 60 degrees?
That's about it. Hope this helps other newbies (with the Leafbike system).
